1 kaz 1.3 Release Notes for Meta-CVS
2 kaz 1.1
3 kaz 1.71 Release 0.17, 2002-07-??:
5     The create command no longer takes a vendor branch. Instead the symbol
6     ``Created-by-Meta-CVS'' is used as the vendor tag to satisfy CVS.
8 kaz 1.72 The grab command no longer does useless synchronization on files that
9     are about to be deleted.
11 kaz 1.73 New purge command, does ``cvs rm'' on deleted files; i.e. F- files that
12     have no mapping.
14 kaz 1.70 Release 0.16, 2002-06-29:
15 kaz 1.67
16     Added new heuristics to grab command. Paths are analyzed to determine
17     move distance. Greater distances reduce the confidence in a move.
18     These rules help sort out grabs in a project where similar or
19     duplicate files are subject to parallel moves, the ambiguity being
20 kaz 1.68 resolved by favoring shorter moves. Word comparisons are case-insensitive
21     now. Common words (those that appear in many files) are ignored when
22     comparing files.
23 kaz 1.67
24 kaz 1.69 New options, --meta and --metaonly. This area of Meta-CVS is cleaned
25     up a little bit. Most reporting commands like log or diff no longer
26     operate on meta files by default; they must be explicitly told to do
27     so with --meta or --metaonly. Only the commit command implicitly includes
28     metafiles by default, and so if this is not wanted, --nometa must be
29     selected. The update command remains special; if it is given file
30     arguments, it does not include meta files. If given no arguments, it
31     does a global CVS up across the entire project.
33 kaz 1.66 Release 0.15, 2002-06-25:
34 kaz 1.61
35 kaz 1.65 Optimized a string splitting routine which is used heavily for processing
36     paths; the result is a noticeable performance improvement in some commands
37     that process large numbers of files.
38 kaz 1.61
39 kaz 1.62 Renamed ``import'' command to ``create''.
41 kaz 1.65 Bugfix: checkout and create showed errors when removing directory, due to
42     broken :postorder support in directory walking function.
43 kaz 1.63
44 kaz 1.65 Bugfix: on failure, checkout was failing to delete the MCVS directory when
45     the checkout was directed to an existing directory.
47 kaz 1.66 New feature: ``mcvs grab'' command imports third-party snapshots to a
48 kaz 1.65 branch. This is invoked in the root directory of the source tree to import.
49     It determines what files have been added and removed in the snapshot, and
50     tries to compute which removes and adds are actually moves. This is done by
51     analyzing the actual contents of the files according to a crude algorithm to
52     do fuzzy comparisons, so that even files which were modified as well as moved
53     are discovered.
54 kaz 1.64
55 kaz 1.60 Release 0.14, 2002-06-21:
56 kaz 1.59
57     Bugfix: mcvs add was broken for files that have no suffix, causing
58 kaz 1.60 the underlying cvs add to fail. This was broken in 0.7 when type
59     handling was added.
60 kaz 1.59
61 kaz 1.58 Release 0.13, 2002-06-06:
62 kaz 1.55
63     Sandbox synchronization now handles the case of two files having
64     the same timestamp. An error is signaled, with interactive resolution
65     to synchronize either way, or do nothing.
67 kaz 1.56 If a file must be deleted on update, and this cannot be done, it
68     is now a continuable error.
70     Bugfix: pass -I ! to cvs import so that it won't ignore some F- files
71     whose suffix is one of the ones cvs ignores by default.
73 kaz 1.57 New command: mcvs remap. The user can move or delete files directly without
74     going through Meta-CVS. When mcvs remap is invoked, it will hunt down the
75     moves and deletions, and reconstruct the mapping accordingly; that is,
76     it remaps the new structure. This command uses inode numbers to identify
77     files; if a file is copied and then the original is deleted, that won't
78     be recognized as a move.
80 kaz 1.53 Release 0.12, 2002-04-18:
81 kaz 1.51
82     Bugfix: remove was broken in 0.10, fixed now.
84 kaz 1.54 Bugfix: status, diff, etc. work in empty project rather than complaining
85     ``. not known to Meta-CVS''.
87 kaz 1.52 The checkout operation now can now populate an existing directory, including
88     the current working directory (mcvs co -d . modulename). Of course, the
89     target directory cannot be an existing Meta-CVS sandbox.
90     This is a useful feature, which allows sandboxes to blend with an
91     existing directory structure.
93     Checkout now uses the same function for generating the sandbox
94     structure as does update. This is now necessary, because local files
95     can be clobbered by the checkout.
97 kaz 1.50 Release 0.11, 2002-04-12:
98 kaz 1.46
99     Bugfix: when branch invokes rtag, it now takes the CVSROOT information
100     from CVS/Root and passes it via -d. This is necessary because rtag does not
101     look at a local CVS subdirectory for this information, only the
102     -d option or the environment variable.
104 kaz 1.48 Command for listing branches added (list-branches or lb). Also shows
105     what sticky tag the sandbox is updated to.
107     Command for switching branches added (switch or sw).
109     Merge detects that working copy is on non-branch tag and bails.
110 kaz 1.47
111 kaz 1.49 Absolute paths can now be specified as file arguments. These are
112     based from the root directory of the sandbox, not the actual filesystem root
113     directory.
115 kaz 1.45 Release 0.10, 2002-04-03:
116 kaz 1.44
117     Automatic merging implemented. Branch is created using branch command,
118     and merging from another branch is done using simple merge command.
119     Meta-CVS maintains the tags to keep track of what has been merged
120     from what branch to what branch.
121 kaz 1.40
122     Bugfix: checkout -d foo bar was complaining about directory bar already
123     existing, even though it should only care about foo.
125 kaz 1.41 The remove command now requires explicit -R option to recursively remove
126 kaz 1.42 a directory. It has more detailed error reporting.
127 kaz 1.41
128 kaz 1.43 The move command has better error reporting.
130 kaz 1.39 Release 0.9, 2002-03-14:
131 kaz 1.37
132     Bugfix: the .cvsignore file is now subject to tagging, status, etc,
133     (unless --nometa is specified, of course).
134 kaz 1.38
135     The mcvs filt command takes -r <revision> or -D <date> parameters.
136     This means to retrieve the MAP file as of the specified revision or
137     date and use that mapping to perform the filtering translation,
138     rather than using MAP-LOCAL.
139 kaz 1.39
140     The mcvs update command takes filename arguments now and also
141     supports the -p option.
142 kaz 1.37
143 kaz 1.36 Release 0.8, 2002-03-13:
144 kaz 1.28
145 kaz 1.29 Bug fixed in mcvs add; it was not ignoring files that are already
146     listed as :ignore in MCVS/TYPES.
148 kaz 1.34 Bug fixed in mcvs move: a target with a trailing slash is now treated
149     as a directory (if it does not already exist and is a non-directory).
151 kaz 1.30 The -d option of mcvs checkout can now be used to override the checkout
152     directory, which is normally the same as the module name.
154 kaz 1.31 The global options --version, --help, -q, -Q and -e are now supported.
156 kaz 1.33 New global options --error-continue and --error-terminate to disable
157     interactive error handling in two different ways.
159 kaz 1.32 Log level of many messages has changed; many messages have been
160     relegated to debug level.
162 kaz 1.35 The import command now creates a .cvsignore file containing the name
163     MAP-LOCAL.
165 kaz 1.24 Release 0.7, 2002-03-09:
167 kaz 1.27 The import command collects a list of the file suffixes and brings up
168     a text editor to allow the user to edit their CVS keyword expansion
169     behavior. This information is kept in a new metafile called TYPES. The
170     add command also updates TYPES; it identifies any suffixes which are new,
171     and brings up an editor. The F- files now carry suffixes, which
172     simplifies interfacing with CVS, and also allows cvswrappers to work.
174     Recursive add works (mcvs add -R ...).
176     New command line option --nometa allows metafiles to be excluded from
177     diff, tag, and other commands; without the option they are inserted
178     into the list of files to be processed.
179 kaz 1.25
180 kaz 1.27 The commit option now takes an optional list of files or directories,
181     just like tag, diff, and others.
182 kaz 1.26
183 kaz 1.23 Release 0.6, 2002-02-16:
184 kaz 1.19
185 kaz 1.27 The add operation was horribly broken in 0.5, it is fixed.
186 kaz 1.21
187 kaz 1.27 User can interactively select whether to clobber local files or leave
188     everything alone. Effects on the mapping file of a mcvs move are undone,
189     if the restructuring is rolled back, or raises a condition that leads
190     to termination.
192     Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
193     during import, and specifies the CVS keyword expansion mode for files
194     having given suffixes, and can also tell Meta-CVS to ignore certain files
195     when importing or adding.
196 kaz 1.22
197 kaz 1.18 Release 0.5, 2002-02-10:
198 kaz 1.14
199 kaz 1.27 Much improved error handling. Filesystem rearranging code performs
200     sanity checks to prevent adds and moves from accidentally clobbering
201     local files. A rearranging gone bad can be rolled back. Effects
202     of a failed mcvs add can also be rolled back.
203 kaz 1.14
204 kaz 1.27 MAP-LOCAL is now sorted in the same way as MAP.
205 kaz 1.15
206 kaz 1.13 Release 0.4, 2002-02-04:
207 kaz 1.10
208 kaz 1.27 CVS is invoked using internal function resembling the xargs utility,
209     which ensures that multiple command lines are generated if necessary to
210     avoid surpassing the operating system limit on argument and environment
211     vector size. This is important when someone wants to diff or stat a
212     subdirectory, which requires Meta-CVS to pick out the individual files
213     at the CVS level.
215     The tag, log, status and annotate commands are now available.
217     The MAP file is sorted on F- file names now, not path names. This
218     improves merging, since files do not move within the file when
219     they are renamed.
220 kaz 1.12
221 kaz 1.5 Release 0.3, 2002-02-02:
223 kaz 1.27 Process termination done is properly in top level handler, by a nonlocal
224     exit. The program properly indicates failed termination when it exits
225     due to an error condition.
227     Corrections are made in the command line option processing. If z is an
228     option that takes an argument, and the argument is -zx, then x is
229     treated as the argument to the option. Long options arguments are
230     recognized properly, according to the --opt=arg convention. The option
231     processing is restructured. Most of the commands now take the
232     appropriate cvs command-specific options.
234     The update algorithm performs dupe checking over the map, which could
235     happen during a merge.
237     Some more bugfixing has been done to the move command. It was still not
238     handling right some cases of an unversioned file being clobbered. Also,
239     it wasn't renaming a directory containing just one file.
241     I did some performance investigation for larger file sets, and
242     ended up rewriting the code that computes filesystem restructuring
243     changes and map duplicates.
244 kaz 1.5
245 kaz 1.4 Release 0.2, 2002-01-30:
247 kaz 1.27 Changed official name from MCVS to Meta-CVS. The move command now
248     performs some filesystem tests so it does the right thing when a versioned
249     file is moved over a non-versioned file, or when a file is moved into
250     a directory not known to Meta-CVS. Factored out reading and writing of
251     map files into functions.
252 kaz 1.4
253 kaz 1.2 Release 0.1, 2002-01-28:
255 kaz 1.27 Support for mcvs diff -u added. The -R option works for mcvs add command.
256     Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
257     mv command when copying a directory to an existing directory.
258 kaz 1.2
259     Release 0.0, 2002-01-27:
260 kaz 1.1
261 kaz 1.27 This is alpha software. It is not complete, and lacks documentation.
262     However, it is already usable in its present state and is being used for
263     version control by its author. If you can program in Common Lisp and would
264     like to help, take a look through the TODO file. Send me patches, ideas,
265     feature requests.
